Car Key Signal Repeater: Everything You Need to Know

What is a Keyless Entry Repeater?

A keyless repeater is a equipment that amplifies the radio frequency from your key fob. This device allows keyless entry to vehicles equipped with proximity keys.

Key signal repeaters are widely utilized for authorized use such as car security research and security assessments.

How Does a Repeater Device Work?

The keyless repeater works by capturing the low-frequency signal from your car key and sending it to your automobile. Here’s the working principle:

1. The repeater device picks up the transmission from the car key
2. It strengthens the radio frequency
3. The amplified signal is relayed to the car
4. The automobile authenticates the transmission
5. Access is granted as if the remote were close
